PUMPIN G RIG.

Application led October 19, 1925. Serial No. 63,465.

' This invention relates to pumping rigs for use withv oil well equipment.

One of the principal objeets'of the invention is to provide a pumping rig which is strong, durable and rigid and yet may be readily set up and taken down so that the r1g can be used over and over again."

, -A further object is to provide-a rig having panying drawings forming Va part of this specification, and in which:

Figure 1 is a fragmentary perspective view illustrating an oil rig constructed in accordance with the present invention,

Figure 2 is a sectional viewshowing how the bearings are mounted on the upper ends of the jack post,

Figure 3 is a' view in horizontal section h .through the Sampson post,

Figure 4 is a View in vertical section von the line 4-4 of Figure 3,

Figuref is a fragmentary view partly in vertical sectionand partly in side elevation illustratingl the major bracing means employed for the Sampson post,

.'Figule' is a detail view taken on the line 6-6 of Figure 7 and illustrating the strue-- ture of one of the bearing brackets provided for the walking beam,.and

Figure 7 is a view in elevation further illustrating the structureof the bearing bracket shown in Figure 6. A

Referringto the 'drawings it will be seen that the-.oil rig embodying the present invention includes a Sampson post1 having its lower end tted `in a collar- 2 integrally formed with a metal base 3 securedby bolts and' nuts 4 to'l a concrete foundation 5. Vertical webs 6' integral with the collar and base serve to strengthen and reinforce the same.

For the purpose lof holding the Sampson post, to the base plate and for bracing-the same longitudinally, adjustable securing -and 1brace rods 7 are provided on the opposite sides of the post 1. Each rod 7 includes a pair of sections, designated at 8 and 9, having their adjacent ends adjustably connected by means of a turnbuckle 10. The lower end lof the section 8 is extended through an opening 12 provided therefor in the web 6. The extreme lower end of the section '8 of each rod is engaged with a nut 13 snugly fittedin a Slot 14 provided' in the base plate below the web. The upper end of eachsection 9 has an eye 15 integrally formed therewith. .The eyes 15 v of the two brace rods are .diametrically oppositc and receive the shank of a 'bolt 16 which passes through bolt holes provided therefor in the plate andV which is held`\against displacement by a nut 17. The nut 17 engages one of the eyes 15 and the head of the bolt en- 7" gages the other eye 15.

At the A upper end of the Sampson post a pair of'bearing brackets 20 are provided, the bearing brackets being arranged diametrically opposite each other, as shown in Fig.

1. Each bearing bracket has a recess 22 in its-inner face in which a portion of the upper end of the Sampson post 1 is fitted, as illus- 'trated to advantage in Fig. 6. At the upper end of each recess 22 a shoulder 23 isl formed .80-

and this shoulder 23 engages the top of the Sampson post. Bolts and nuts 24 fasten the bearing brackets to the Sampson post. Bear-- ings are provided on the bearing brackets and in these bearings tru'nnions 26 of a 35 mounting member-27 are oscillatably fitted. The mounting member 27 is secured to the ing beam 28.

with a laterally extending ,lug 38 having a socket 39 ther'emand an openlng 40. extendving therethrough. A bracket,'des'ignated generally at 41, is also provided inthe major racing unitand has an attaching plate 42 105 bolted, as at'43, to a portion of the foundation of the rigging. l This'l bracket 41 also has a lug 42 which inclines upwardly'therefrom and 4which is formed with a socket 44 and a transverse opening 45.- Thel socket 44 is alined 211 with the socket 39 'and the openings-40 and l 45 are also aline'd. A rigid and heavy brace bar 46 is provided sockets 39 and 44. A. tensioning rod, designated generally at 47 is also. incorporated in the major bracing unit and is made u p ofsections 48 and 49 adjustably connected to Aeach other by means of a turnbuckle 50. The upper nd thesame. The projecting portion of thesecti 11549 has a nut 51 threaded thereon and engaging a portion of the'lug 4 2. The lowerend portion of the section 48 extends 'through the opening 45 and is engaged by the nut 52.; lVith this lars -63 integrally -formed 64, websf being provided to reiriforceithej collars and ba's'e plates. The bearings 61 are 1 mounted on top plates 66 ha'vin'g reduced5dearrangement the tensioning rod 47may be placed under proper tension tohold the brace bar in its sockets. Y The walking beam is oscillated fromithe bull Wheel. 60 in the usual manner, but the shaft of thebull wheelis journaled in bearings 61 carried by check posts .62 constructed and mounted in accordance with the presgent invention, The jack posts although dif-i -ering in some respects from the Sampson post have common features ofl advantage therewith. As shown' in Figures. 1 and 2 the jack posts have 67 which snugly fit in the pending extensions posts 62. Like Athe bolts upper ends of the 16, plates`66 provide transversely extending cross members engaging with the post on adj ustably which they are mounted and co-operable with brace rods 68 lmade up buckle' 71, Y.
